Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an apparatus parameter adjustment method according to an embodiment of the present invention. The present embodiment is applicable to the case when the parameters of the video output apparatus are adjusted, particularly to the case when the user sets the output resolution of the apparatus to be high resolution. The method may be performed by a device parameter adjusting apparatus, which may be implemented in software and/or hardware, for example, the device parameter adjusting apparatus may be configured in a device (e.g., a video playing device). As shown in fig. 1, the method specifically includes:
and S110, acquiring the actual resolution of the currently played video.
In this embodiment, in order to solve the technical problem in the prior art that other additional functions occupying live broadcast resources are unavailable after a user sets a high output resolution, by starting the resolution adaptive system, when it is detected that the video resolution is a non-set high output resolution, the output resolution is automatically switched to the current video resolution, so that the effect that in the use process of the user, if the watched current video is a low resolution video, other additional functions occupying live broadcast resources can still be used is achieved.
Optionally, when a video playing instruction or a video switching instruction is monitored, the actual resolution of the currently played video is obtained. In this embodiment, the monitoring of the video playing instruction or the video switching instruction may be performed through monitoring the preset interface.
In this embodiment, the actual resolution of the currently played video may be obtained through the playing parameters of the currently played video, or the actual resolution of the currently played video may be determined through the playing picture of the currently played video.
In an embodiment of the present invention, the obtaining an actual resolution of a currently playing video includes:
the method comprises the steps of obtaining a single-frame playing event of a currently played video through a preset notification interface, and determining the actual resolution of the currently played video according to the single-frame playing event.
Optionally, a single-frame playing event of the currently played video may be intercepted through a preset notification interface, and the actual resolution of the currently played video is determined according to a single-frame picture parameter included in the single-frame playing time. It can be understood that, when a video playing instruction or a video switching instruction is detected, at least one single-frame playing event of a currently playing video may be intercepted through the preset notification interface, and for each single-frame playing event, a single-frame picture parameter of the currently playing single-frame playing event is determined. Optionally, the first frame event of the currently played video may be intercepted through a preset notification interface.
In an embodiment of the present invention, the determining the actual resolution of the currently played video according to the single frame playing event includes:
analyzing the single-frame playing event to obtain the horizontal resolution and the vertical resolution of a single-frame picture corresponding to the single-frame playing event in the horizontal direction and the vertical resolution in the vertical direction, and determining the actual resolution according to the horizontal resolution and the vertical resolution.
In this embodiment, for each captured single frame playing event, the single frame event is analyzed to obtain the resolutions of the single frame image corresponding to the single frame event in the horizontal direction and the vertical direction, and finally the resolution of the captured single frame image is determined, and the determined resolution is used as the actual resolution of the currently played video.
Illustratively, if the horizontal resolution of the acquired single frame picture is 1024 and the vertical resolution is 768 in the intercepted single frame playing event, the resolution of the single frame picture is 1024 × 768, and the actual resolution of the currently played video is further determined to be 1024 × 768.
S120, obtaining an initial output resolution of the video playing device, and matching the actual resolution with the initial output resolution when the initial output resolution is not less than a preset resolution threshold.
In this embodiment, the initial output resolution of the video playing device may be an output resolution set by a user, and when the output resolution is not set by the user, the initial output resolution of the video playing device is an output resolution that is set by default when the video playing device leaves a factory.
Optionally, after the actual resolution of the currently played video is obtained, the initial output resolution of the video playing device is obtained, whether the initial output resolution is high resolution is determined, when the initial output resolution is not less than a preset resolution threshold, the initial output resolution is determined to be high resolution, and the output resolution adaptive function is started. In one embodiment of the present invention, the preset resolution threshold is 3840 × 2160 and/or 4096 × 2160. Currently, there are few video resources with a resolution of 4K and above, and therefore, the preset resolution threshold may be set to 4K resolution (3840 × 2160 or 4096 × 2160), but as the technology advances, the preset resolution threshold may be set to higher resolution.
In an embodiment of the present invention, the obtaining an initial output resolution of a video playback device includes: and acquiring the initial output resolution of the video playing equipment by calling a resolution acquisition interface. Optionally, the initial output resolution of the video playing device may be obtained by calling a preset resolution obtaining interface.
In this embodiment, the steps of acquiring the actual resolution of the currently played video and determining whether the output resolution of the video playing device is the high resolution are not limited. That is, the operation of obtaining the actual resolution of the currently played video in S110 may be performed first, and then the operation of determining whether the output resolution of the video playing device is high resolution in S120 may be performed; it is also possible to first perform the operation of determining whether the output resolution of the video playback device is high resolution in S120, and then perform the operation of acquiring the actual resolution of the currently played video in S110.
And when the initial output resolution of the video playing device is not less than the preset resolution threshold, matching the actual resolution with the initial output resolution to determine whether the actual resolution of the currently played video is the same as the initial output resolution of the video playing device. Illustratively, when the initial output resolution of the video playback device is 4096 × 2160 and the preset resolution threshold is 4096 × 2160, indicating that the high output resolution is set by the user, the actual resolution is matched with the initial output resolution to determine whether the currently played video is a high output resolution video.
And S130, if the actual resolution is smaller than the initial output resolution, adjusting the initial output resolution to a target output resolution to start a preset additional function of the video playing device.
In this embodiment, when the actual resolution is smaller than the initial output resolution, it indicates that the currently played video is not the high-output resolution video, that is, the resource occupation of the video resource of the currently played video to the video playing device does not affect other additional functions occupying the live broadcast resource, and the initial output resolution of the video playing device may be adjusted, so that the preset additional function of the video playing device can be normally used. In this embodiment, the initial output resolution of the video playing device may be adjusted to a target output resolution to start a preset additional function of the video playing device, where a value of the target output resolution is not greater than a value of the actual resolution.
Preferably, the value of the target output resolution is equal to the value of the actual resolution. The initial output resolution of the video playing device is adjusted to the target output resolution equal to the actual resolution, so that the use of other preset additional functions of the video playing device can be realized under the condition of ensuring that the video playing definition is not influenced. Optionally, the preset additional function includes at least one of a program predictive playing function and a picture-in-picture function.
When the actual resolution is not less than the initial output resolution, the currently played video is represented as a high-output resolution video, the resource occupation of the video resources of the currently played video on the video playing device can affect other additional functions occupying live broadcast resources, and the initial output resolution of the video playing device is not adjusted.
In this embodiment, the switching when the output resolution of the current video playing device is switched to the actual resolution of the currently played video is the switching under the resolution self-adaptation condition, and the judgment result of the next television resolution self-adaptation judgment module will not be affected. If the user sets the television resolution to be 4K, after the user performs channel switching operation, the video resolution is found to be 1080P50HZ, namely, the television resolution setting module is triggered to be set to be 1080P50 HZ; but when the user switches channels next time, as long as the user does not actively set the television resolution, the television resolution obtained by the television resolution learning module is still 4K.
The embodiment of the invention obtains the actual resolution of the currently played video; acquiring an initial output resolution of video playing equipment, and matching the actual resolution with the initial output resolution when the initial output resolution is not less than a preset resolution threshold; if the actual resolution is smaller than the initial output resolution, the initial output resolution is adjusted to a target output resolution to start a preset additional function of the video playing device, wherein the value of the target output resolution is not greater than the value of the actual resolution, so that the additional function can be used when a user sets a high output resolution but the video resource is a non-high resolution resource, and further user experience is improved.
On the basis of the above scheme, after the initial output resolution is adjusted to the target output resolution, the method further includes: restoring the target output resolution to the initial output resolution upon detection of a video switching event.
In this embodiment, after the output resolution adaptive function of the video playing device is started, when a video switching event is detected, the target output resolution of the video playing device is restored to the initial output resolution, so that the situation that the playing effect of other played videos is changed by the video playing device due to the adjustment of the output resolution of the currently played video is further avoided. For example, when the initial output resolution of the video playing device is 3840 × 2160 and the actual resolution of the currently played video is 1920 × 1080, the output resolution of the video playing device is adjusted to 1920 × 1080 in order to turn on other additional functions of the video playing device, and when the user needs to watch other video resources and perform video switching, the output resolution of the video playing device needs to be adjusted back to 3840 × 2160, so that the video playing device can play at the resolution of 3840 × 2160 when the resolution of other video resources is 3840 × 2160.
